  • Publication number: 20160196797
    Abstract: A display panel is divided into multiple areas respectively driven by multiple drivers, and the multiple areas are adjacent to each other along a first direction. An object moves along the first direction between a first frame and a second frame and is displayed on the display panel. The moving speed of the object is compared with a reference speed. A main compensation frame is added between the first frame and the second frame. A first high speed compensation frame is added between the first frame and the main compensation frame when the moving speed is higher than or equal to the reference speed. A first low speed compensation frame is added between the first frame and the main compensation frame when the moving speed is lower than the reference speed, and the first low speed compensation frame is different from the first high speed compensation frame.

  • Patent number: 9312710
    Abstract: Disclosed is a charging cradle for a headset device, which includes a housing with a surface providing a mounting depression, and a cover with a transparent surface pivotably connected to the housing so as to open and close the mounting depression. The headset device is mounted in the mounting depression so as to charge an internal battery pack provided in the headset device. The cradle protects the headset device under charging, enabling the user to observe the charging state without opening it. An earphone cover for a headset device includes a projected semi-circular fixing ring for preventing the earphone from being removed from the ear. The earphone cover is provided in various sizes to fit a user's ear size, and may be rotated to change the rotational position of the fixing ring so as to enable the user to put the headset device selectively on the right or left ear.
